T2 relaxometry of the hippocampus at 3T.
BACKGROUND AND PURPOSE T2 mapping is useful for identifying and quantifying abnormalities of the hippocampus and amygdala. It is particularly useful in the presurgical evaluation of patients with temporal lobe epilepsy and for the identification of bilateral hippocampal sclerosis (HS). The purpose of this study was to implement and validate a dual-echo method for producing coronal T2 maps with ...

متن کاملRobust myocardial T2 and T2* mapping at 3T
PURPOSE Intramyocardial hemorrhage and area at risk are both prognostic markers in acute myocardial infarction (AMI). Myocardial T2 and T2 * mapping have been used to detect such tissue changes at 1.5T but these techniques are challenging at 3.0T due to additional susceptibility variation. We studied T2 and T2 * myocardial mapping techniques at 3.0T on a system employing B1 shimming and compare...

متن کاملT1 and T2 Metabolite Relaxation Times in Normal Brain at 3T and 7T
Proton magnetic resonance spectroscopy (MRS) is a powerful noninvasive tool that has been widely used for the assessment of brain metabolites and the investigation of normal and abnormal metabolism in brain tissue. With the availability of improved hardware and acquisition techniques, in vivo single-voxel 1H-MRS and multivoxel magnetic resonance spectroscopic imaging (MRSI) can offer new possib...
